Hi Kwan, re: > The system administrator installed byacc (as well as the other packages in > your last email) before the weekend. So I tried recompiling McIDAS 2016 > this morning. First, I did 'make clobber' and then 'make mcx'. But it > ended with an error similar to my last attempt. I am attaching 'makelog' > for you to check. The error reported in 'makelog' shows that the environment in which you are trying to build v2016 is not correct: /bin/sh ./libtool --tag=CC --mode=link gcc -O -no-undefined -export-dynamic -version-number 16:21:0 -Wl,--version-script=libpng.vers -L/awips2/python/lib -L/export-5/ncosrvnfs-cp/nawips2/os/linux2.6.32_x86_64/lib -s -L/usr/X11R6/lib64 -L/export/wpc-lw-fobdev5/kkong/mcidas/mcidas2016/src/../zlib -lz -o libpng16.la -rpath /export/wpc-lw-fobdev5/kkong/mcidas/lib png.lo pngerror.lo pngget.lo pngmem.lo pngpread.lo pngread.lo pngrio.lo pngrtran.lo pngrutil.lo pngset.lo pngtrans.lo pngwio.lo pngwrite.lo pngwtran.lo pngwutil.lo -lm -lz -lm libtool: link: gcc -shared -fPIC -DPIC .libs/png.o .libs/pngerror.o .libs/pngget.o .libs/pngmem.o .libs/pngpread.o .libs/pngread.o .libs/pngrio.o .libs/pngrtran.o .libs/pngrutil.o .libs/pngset.o .libs/pngtrans.o .libs/pngwio.o .libs/pngwrite.o .libs/pngwtran.o .libs/pngwutil.o -L/awips2/python/lib -L/export-5/ncosrvnfs-cp/nawips2/os/linux2.6.32_x86_64/lib -L/usr/X11R6/lib64 -L/export/wpc-lw-fobdev5/kkong/mcidas/mcidas2016/src/../zlib -lz -lm -O -Wl,--version-script=libpng.vers -Wl,-soname -Wl,libpng16.so.16 -o .libs/libpng16.so.16.21.0 /usr/bin/ld: /export-5/ncosrvnfs-cp/nawips2/os/linux2.6.32_x86_64/lib/libz.a(crc32.o): relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC /export-5/ncosrvnfs-cp/nawips2/os/linux2.6.32_x86_64/lib/libz.a: could not read symbols: Bad value collect2: ld returned 1 exit status make[2]: *** [libpng16.la] Error 1 make[2]: Leaving directory `/export/wpc-lw-fobdev5/kkong/mcidas/mcidas2016/libpng' make[1]: *** [all] Error 2 make[1]: Leaving directory `/export/wpc-lw-fobdev5/kkong/mcidas/mcidas2016/libpng' make /export/wpc-lw-fobdev5/kkong/mcidas/mcidas2016/libpng: FAILED The attempt to use the system-installed libz.a instead of the version that is included as part of the McIDAS-X distribution indicates the environment problem. Question: - did you login using the McIDAS-specific .cshrc file when you tried to do the build?
